GAS osi-VAPOR LAMP.

SPECIFICATION forming part of Letters patent No. 728,265, dated May 19,190s Application filed August 15, 1902. Serial No. 119.701. (No model.)

To all whom it may concern/: q c

Beitknown that I, ARTHUR MENDEga citizen of the United States, residingin the city of New York, in the county of New Yorkand State of New York,have invented cer-tain new and useful Improvements in Gas or VaporLamps, of which the followingis a speci- `fcation.

This invention relates to gas or `vapor xo lamps; and it consistssubstantially in the improvements hereinafter particularly described.

The invention has reference more especially to that class of gas orvapor lamps in which I5 ordinary gas is combined with atmospheric airaud consumed at one or more. burners either for heating or illuminatingpurposes; and one of the principal objects of the invention is toprovide a gas or vapor lampof this 2o kind in which perfect admixtureofgas and air is had, resulting in a clear flame of great brilliancy andintensity.

A further object of the invention is to provide a gas or vapor lampwhich is simple in z 5 the construction and organization of elements orparts thereof and one which is effective and reliable in use oroperation. v

The above and additional objects are attained by means substantiallysuchv as are illustrated in the accompanying drawings, in which-u Figurel is an enlarged perspective` View,l

in, part verticalsection, of the gas-and air burner employed in myimproved gas or vapor lamp, and Fig. 2 is a side View of .the`

lamp, on reduced scale. Fig. 3 is aside view of the main and auxiliaryor pilot burners shown in'Fig. 2. Y

Before proceeding with a more-detailed de'- 4o scription it may bestated that my improved'- gas or vapor-lamp comprises a specially-con',-

structed fitting, in the main body of which' works a gas-admission cockor valve having a lateral port which may be made to register.'

4; with a port communicating with the interior of a branch of thefitting, in which branchis screwed or otherwise fastened an end of agassupply pipe leading from any point of support therefor. Secured inthe upper end of 5o the mainbody of the fitting is a burner-tube havingat the upper end thereof preferably duplicate main' burners for thecombined gas and air, the said'burner-tube having air-inlet openings andotherwise specially constructed, as hereinafter specifically described.Leading preferably from thesides of4 the branch of the fitting areduplicate small gas-tubes extending upwardly through and slightly abovethe main burners', the upper ends of which tubes constitute pilot orever-lighted 6c burners by which ignition of the gas mixture is effectedat the main burners Whenever the gas-supply is turned on-to said. mainburners. The gas-ad mission cocker valvelis formed with a port for theoperative end of a needlevalve for controlling the gas-supply to theburner-tube, the said .gas-admission cock or valve being of specialembodiment, and the saidl needle-valve isi"V provided with special meansfor adjusting or regulating the same. 7o The interior of saidburner-tube'constitutes practically a mixing-chamber forthe gas and air,and inclosing theburner-ittingis a cage which supports an ordinary glassglobe havling a reflector at the top, and-up,o'n which 75 globe is achimney or'tube surmoupted byanother reiiector, vall as will hereinafterfully appear. j

,Specic referenceY beinghad to the accompanying drawings by thedesiguatingcharac- .8O i 'ters marked thereon,-A represents aspeciallyconstru cted fitting, the body a of which is hollow, as shown,and theinner surface of which is conical or tapering upwardly, asindicated at b, said tting having a lateral upt'urned 85 branch c,communicating with the interior .of body ct by means of aportd i-n theside of the latter. Screwinginto or-otherwise ltting the end of saidupturned branch c is the lower end of an ordinary gas-supply pipe e,which may 9o lead from a ceiling .or vother support, and

snugly fitting within the hollow body a of Ythe fitting A is aconicalxcock or 4plug-Valve B, which is also preferably hollow,.asshown,

and is formed with a lateral port f, which may be carried into and outof register. with port d, as desired, by simply turnin'gthe'fcock orvalve B in one direction"orthe'other, the said cock or valve beingformed or provided at its lower end with a shank or stem g, which worksrco or turns i-n an opening in a nipple or cap h, which is threadedexternally to screw into the lower end of the hollow body a of thefitting, as shown, and surrounding the said shank or stem is a springexerting its tension between the said nipple or cap and the lower end ofthe said cock or valve to constantly urge the latter' upwardly withinthe said hollow body, so as to prevent leakage of gas from the fitfing.The pressure of said spring may beincreased or diminished by properlyadjusting the nipple or cap h, as is apparent. The said shank or stem gis provided with a central longitudinal opening, through which Vpassesfrom beneath a needle-valve C, the upper pointed end m of whichregulates the passage of gas or vapor through a port n in the upper endof cock or valve B, the sides of said port being also conical. (See Fig.l.) The lower portion s of said needle-valve is threaded to fit athreaded opening s in the shank or stem, the latter being formed orprovided at its lower end with a key 10, which may be taken hold of bythe hand for the purpose of turning or manipulating the cock or valve Bto turn on and shut off admission of gas to the interior thereof. Thelower end of the needle- Valve is notched at u to receive the end of ascrew-driver or other implement which may be conveniently employed toturn said needle-valve when desired to adjust the same.

The upper end of the body a of the fitting A is recessed and interiorlyscrew-threaded at u to receive the corresponding exteriorlythreadedlower end of a burner-tube D, provided around its lower portion withair-inlet openings w, the said tube being surmounted by preferablyduplicate main burners E E and the interior thereof constituting amixing-chamber for the gas and air passing to said burners. The locationof the gas-exit port n in the end of cock or valve B is such withrespect to said air-inlet openings that the force of gas issuing fromsaid port induces currents of air to enter such openings and mix withthe gas in a manner quite apparent. Each of the said main burners isprovided with a lateral projection a; for receiving the lower end of thesupporting-rod y of an ordinary incandescent mantle ll, the said rodsbeing secured in place by set-screws z, as shown.

Fitting in a hollow plug l2, projecting from each side of the upturnedbranch c of the fitting A, is the lower end of a small gas-tube ll, saidtubes leading upwardly throughv and above the main burners from beneath,as shown, and the upper ends 16 thereof constituting auxiliary or pilotburners which may be kept constantly lighted to serve to ignite the gasmixture at said main burners whenever a supply of gas is caused to flowthereto. Said auxiliary or pilot burners are constantly supplied withgas frornthe branch c of the fitting, which branch, as is understood, isin open communication with the gas-supply pipe e. Preferably I employ avalve 20, working in each of said plugs l2, for cutting oil the passageof gas to the said pilot or auxiliary burners, if desired.

Screwing upon the lower externally-threaded end 25 of the body ct of thefitting A is a collar or ring 26, between the upper edge of which and ashoulder 27 on the body is clamped a cage or holder 30 for an ordinaryglass globe 32, the lower edge of which fits within a ring 33 on theupper edge of said cage or holder and is fastened by a set-screw 34, thecage or holder being formed, preferably, all around wilh air-inletopenings 35. Located at the upper part of the globe is a refiector 3S,which may be integral with or attached to a chimney or flue 40, whichalso is preferably surmonnted by a reflector 4:2, suitable means 43being provided above said refiector whereby the lamp structure may besuspended from any suitable support therefor. As thus constructed andorganized it will be seen that my improved gas or vapor lamp is simpleand effective and also that the same may be manufactured atcomparatively small cost.

It is apparent that l am not limited to the precise details ofembodiment herein illustrated and described, since departures may bemade therefrom coming within the scope of my invention.
